Embodiment Construction

[0018] The three-dimensional three-dimensional modeling method for a large number of books in a virtual library includes establishing a book catalog database data growth model, realizing real-time dynamic synchronous shelving of catalog data and establishing a "book-level" virtual reality scene model.

[0019] (1) Establishing a data growth model for the library catalog database

[0020] The book catalog contains the basic information of the books and is arranged in a certain order. The number of catalogs in different libraries ranges from hundreds of thousands to millions.

[0021] The growth law of the library catalog database directly affects the synchronous data update of the library catalog data in the virtual reality library, and the establishment of the catalog database data growth model can directly serve the problem of synchronous shelving.

[0022] The growth law of the catalog data updated according to the library catalog database in each academic year conforms to ...

Abstract

The invention provides a three-dimensional modeling method of vast books of a virtual library, comprising the following steps: building a book catalogue database data growth model; realizing real-time dynamic and synchronous shelving of the book catalogue data according to the book catalogue database data growth model; and building a 'book-grade' virtual realistic scene model. The step of building a 'book-grade' virtual realistic scene model comprises: scanning, and registering the data of entity books; according to the picture of a single book and the basic attribute of the book, modeling to generate a single book mode; gradually generating each book so as to form a book model database; combining book shelving information, book reservation information, book state and the basic attribute of the book; successively displaying the virtual realistic scene of the library books, physical book reservation site bookshelves and physical book reservation sites by the virtual realistic technology; and finally, forming the general virtual realistic scene of the library.

Description

technical field [0001] The invention relates to a modeling method, in particular to a three-dimensional modeling method for massive books in a virtual library. Background technique [0002] With the development of global network digital technology and the rapid development of digital resources, many colleges and universities have established digital libraries, which have developed into an open and highly complex library where multiple media resources, multiple system platforms run in parallel, and multiple service modes coexist. comprehensive system. [0003] However, at present, the representative and few virtual display introductions of university libraries in the world are all based on 2D forms. Readers can only obtain the shelf position of the book from the 2D query system, and cannot freely choose the observation point, let alone obtain other information such as the cover image, side elevation, title, page number, and content of the book in the 3D environment. It limi...
